Moreover, the compounds of the formula (1) according to the invention can, if they contain a sufficiently acidic group, such as a carboxyl group, be converted, if desired, into their salts with inorganic or organic bases, in particular, for pharmaceutical use, into their physiologically acceptable salts. Bases which are suitable for this purpose are, for example, sodium hydroxide, potassium hydroxide, calcium hydroxide, lysine, cyclohexylamine, ethanolamine, diethanolamine and triethanolamine.

1-(3,5-dimethoxyphenyl)-4-(4-quinolyl-carbonyl)piperazine

2 g (11.5 mmol) of quinoline-4-carboxylic acid were suspended in 80 ml of DMF. With stirring, 1.74 g (17.2 mmol) of N-methylmorpholine and then a solution of 8.95 g (17.2 mmol) of Py-BOP (1-benzotriazolyltripyrrolidinophosphonium hexafluorophosphate) and 2.56 g (11.5 mmol) of 1-(3,5-dimethoxyphenyl)piperazine in 25 ml of DMF were added to this mixture. The mixture was stirred at RT for 12 h, the DMF was distilled off under reduced pressure and the residue was purified on a silica gel column (Kieselgel 60, from Merck AG, Darmstadt) using the mobile phase dichloromethane/methanol/25 percent ammonia (90:10:1 v/v/v).
